Retrieval of components from JSON array of objects

I have a JSON array containing objects stored on the server. How can I access the first object to print its contents? The data is in the following format:

[
  {
   "eventId": "8577",
   "datasetId": "34",
   "nodeId": "8076",
   "typeId": "4",
   "type": "TempAndHum",
  "status": "Temp : 35, Hum : 83",
  "datasetName": "test active set",
  "mode": "shared",
  "xmlFragment": "Absent",
  "gpsLat": "-23.549999",
  "gpsLong": "-46.633301",
  "contributor": "SanatIITD",
  "addedOn": "2015-04-21 08:03:16",
  "updatedOn": "2015-04-21 08:03:16"
  },
 {
  "eventId": "8576",
  "datasetId": "34",
  "nodeId": "8076",
  "typeId": "4",
  "type": "TempAndHum",
  "status": "Temp : 34, Hum : 81",
  "datasetName": "test active set",
  "mode": "shared",
   "xmlFragment": "Absent",
  "gpsLat": "-23.549999",
  "gpsLong": "-46.633301",
  "contributor": "SanatIITD",
  "addedOn": "2015-04-21 08:03:11",
 "updatedOn": "2015-04-21 08:03:11"
 },
 {
    "eventId": "8575",
   "datasetId": "34",
   "nodeId": "8076",
   "typeId": "4",
   "type": "TempAndHum",
   "status": "Temp : 33, Hum : 80",
   "datasetName": "test active set",
   "mode": "shared",
  "xmlFragment": "Absent",
  "gpsLat": "-23.549999",
   "gpsLong": "-46.633301",
   "contributor": "SanatIITD",
  "addedOn": "2015-04-21 08:03:05",
  "updatedOn": "2015-04-21 08:03:05"
 }
]

I attempted to access the data using data[0], but was only able to print "[". I also tried using JSON.stringify followed by splitting with ",", but that only returned the first element of the object, not the entire first object within the curly braces. I aim to print the entire first object without having to print each element separately. Is there a way to access it like an array using document.getElementById("Id")=myData[0]? Please provide a solution. Thank you in advance.

Answer №1

Start by using 

var dataArray = JSON.parse(dataString)
, as your data is currently in string format.

After that, you can access the first element of the dataArray with dataArray[0]
